Should IS DISTINCT FROM work with ANY()?

Howdy,

Shouldn't this work?

postgres=# SELECT 'foo' IS DISTINCT FROM ANY(ARRAY['foo']);
ERROR: syntax error at or near "ANY"
LINE 1: SELECT 'foo' IS DISTINCT FROM ANY(ARRAY['foo']);

Seems to me that IS DISTINCT FROM is just another operator, like =,
and so it should work with ANUY(), no?

Tested on 8.2 and 8.3.

Thanks,

David
